Microsolvated biomolecules are promising model systems to study the corresponding light-induced dynamics of molecules in solution [1]. Due to the still manageable complexity of the small clusters, atomic, molecular, and optical physics methods can be used for the analysis and characterization of their dynamics. Coulomb explosion imaging is one of those methods that can be applied to distinguish the various reaction channels present. Furthermore, it allows to determine the orientation of molecules or clusters in the gas phase [2]. In this presentation, our findings on the ionization dynamics of pyrrole-water and water-dimer will be presented. In addition, we will discuss our results on the field-free alignment of complex molecules in the gas phase using pulse shaping [3].
